Effective Techniques for Safely Removing Submersible Well Pumps from Deep Water Sources

Removing Submersible Well Pump A Comprehensive Guide


Submersible well pumps are crucial components of many water supply systems, especially in rural areas where groundwater is the primary source of water. These pumps are designed to operate underwater, making them efficient at delivering water directly from the ground to the surface. However, there may come a time when you need to remove a submersible well pump for maintenance, repair, or replacement. This article provides a step-by-step guide on how to effectively remove a submersible well pump, ensuring that the process is safe and efficient.


Understanding the Components


Before diving into the removal process, it’s essential to have a basic understanding of the components involved. A submersible well pump typically consists of


1. Pump Motor This is the motor that drives the impellers to pump water. 2. Pump Body The main structure that houses the pump and motor. 3. Discharge Head The above-ground portion where pipes connect to the delivery system. 4. Electrical Wiring Powers the motor and may need to be disconnected. 5. Drop Pipe The pipe that carries water from the pump to the surface.


Safety Precautions


Safety should be your top priority when removing a submersible well pump. Follow these precautions


- Turn off the power supply to the pump to prevent electrical accidents. - Wear appropriate personal protective equipment, such as gloves and safety goggles. - Ensure the wellhead is stable and free from obstructions.


Tools Required


To remove a submersible well pump effectively, you’ll need the following tools


- Adjustable wrench - Pipe wrench - Pliers - Screwdrivers - Rope or cable for pulling - Bucket or container for catching water

Step-by-Step Removal Process

1. Prepare the Wellhead Clear the area around the wellhead. Inspect the discharge head for any screws or bolts that need to be removed.


2. Disconnect the Power Before starting the removal, disconnect the electrical power supply. Locate the circuit breaker that serves the well and turn it off to prevent any accidental start-up.


3. Remove the Discharge Head Unscrew the bolts or nuts that hold the discharge head in place. Carefully lift it off to expose the drop pipe and electrical connections.


4. Disconnect the Plumbing If there are any water pipes connected to the discharge head, disconnect them using an adjustable wrench. Ensure that you have a bucket ready to catch any residual water that may spill during this process.


5. Disconnect Electrical Wiring Carefully disconnect the electrical wires from the pump motor. Take note of how the wires are connected as you will need to reconnect them later.


6. Prepare for Pump Removal Secure a rope or cable around the pump for added leverage. Ensure that the rope is firmly attached and can handle the weight of the pump.


7. Pull the Pump With the help of another person, gently begin pulling the pump out of the well. It's essential to pull it straight out to avoid damaging the drop pipe or causing the pump to get stuck.


8. Inspect and Clean Once the pump is out, inspect it for wear or damage. Clean the pump and check the drop pipe for any debris or blockages.


Conclusion


Removing a submersible well pump can seem daunting, but with the right tools and techniques, it can be accomplished safely and efficiently. Regular maintenance and inspections can help prolong the life of your pump and ensure a steady supply of water. If you are uncertain about any part of the process, it’s advisable to consult with or hire a professional plumber or well technician. They can provide expertise and ensure that your well system remains functional and reliable.
